High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.

Overcoming Out‐of‐Plane Conduction by Changing Nanosheet Morphology

Advanced Science, EarlyView.
HTaWO6 membrane made of stacked nanotubes exhibits high out‐of‐plane proton conductivity of 1.7 mS/cm. High current density (1.26 A cm−2) and power density (294 mW cm−2) indicate the potential as a fuel‐cell electrolyte. The morphology‐driven strategy establishes topology engineering as a new design principle for efficient ion transport in two ...

Protonation Modification of Commercial OPBI as Binders Toward High‐Performance High‐Temperature PEM Fuel Cells

Advanced Science, EarlyView.
Commercial OPBI binders is regulated via a facile formic‐acid protonation strategy without disrupting the polymer backbone. Protonation introduces positively charged benzimidazole sites, inducing interchain electrostatic repulsion that loosens chain packing, enlarges intermolecular spacing, and promotes uniform binder dispersion over catalyst surfaces.
